7V, 7A SynchroFET™ Complementary Drive Synchronous Half-Bridge

Designed with the Pentium® in mind, the Intersil SynchroFET family provides a new approach for implementing a synchronous rectified buck switching regulator. The SynchroFET™ replaces two power DMOSs, a Schottky diode, two gate drivers and synchronous control circuitry.

Features
• Complementary Drive, Half-Bridge Power NMOS
• Use With Low-Cost Single-Output PWM Controllers
• Improve Efficiency Over Conventional Buck Converter with Schottky Clamp
• Minimum Deadtime Provided by Adaptive Shoot-Through Protection Eliminates External Schottky
• Grounded Case for Low EMI and Simple Heatsinking
• Low Operating Current
• Frequency Exceeding 1MHz
• Dual Polarity Input Options
• All Pins Surge Protected

Applications
• 5V to ≤3.3V Synchronous Buck Converters
• 3.3V to ≤2.9V Synchronous Buck Converters
• Pentium Power Supplies
• Bus Terminations (BTL and GTL)
• Drive 5V Motors Directly from Microprocessor
